BALITHERM® IONIT is the nitriding and nitrocarburizing process for all sintered materials, all types of steel (also high-alloyed steels) and non-ferrous metals.

Plasma nitriding is an industrial surface hardening process in which molecular nitrogen and hydrogen are ionized under vacuum and  react with an iron substrate at temperatures between 350°C and 600°C.

The addition of carbon to the nitriding process leads to plasma nitrocarburizing, which creates an especially hard, wear resistant compound layer. Nitrocarburizing moreover significantly reduces the tendency of iron to react with other materials in the environment, for example lubricants (significantly reduced tribo-oxidation).
